Publish once. Distribute everywhere.
The Collect24 Registry API lets external systems — gallery platforms, artist websites, collection management software, museum systems and website builders — publish, retrieve and synchronise artwork data in the global art registry.
The API is not a separate database. It is a permissioned, read-and-write layer over exactly the same records collect24.art serves, with one source of truth per artwork.

Permanent Collect24 Art IDs
Every artwork in the registry carries a permanent Collect24 Art ID such as C24-4711. The ID is issued once and never changes — not when the work is sold, not when it moves between a gallery, a museum and a private collection, not when its status, availability or location changes.
Store the collect24_id in your own system. It is the stable join key between your inventory and the registry, and it is what public Collect24 pages, certificates and webhook payloads refer to.

Rights, licensing and responsibilities
Access to the API does not grant any right to redistribute copyrighted images or other third-party content. Much of the registry originates from museum open access programmes, galleries and artists, each with its own licensing and attribution terms. You remain responsible for complying with the rights and licence restrictions attached to the source data you retrieve, including image reuse, credit lines and commercial use.
The API exposes only data that is already public on collect24.art. Owner identities, private notes, valuations, acquisition prices, documents, offers and internal identifiers are never returned — see the privacy policy.
Keys are server-to-server credentials. The API sends no cross-origin headers, so keys must never be shipped in a browser bundle, mobile app or public repository.
